UK Economy Grows 0.7% in Third Quarter, Its Fastest Pace in Two and a Half Years as AI Spending Lifts Services

Britain’s economy grew by 0.7% in the third quarter of 2026, its fastest expansion in two and a half years, as spending on artificial intelligence lifted activity across the services sector and defied predictions of a slowdown. The Office for National Statistics said on Thursday that gross domestic product rose 0.7% in the July-to-September period, up from 0.5% in the second quarter and the strongest quarterly expansion since the first three months of 2024. The annual growth rate picked up to 1.9%, its strongest reading since the final quarter of 2024, and on a rolling three-month basis growth was the fastest since May. The figures extend a strong first half of the year and arrive weeks after the government’s October budget, handing the chancellor a better economic backdrop than the official forecasts assumed. This is the story of the UK economy Q3 2026 GDP growth November 2026, what drove it, what lagged behind, and what it means for households, businesses and interest rates in the months ahead.

1. The Headline Number: Growth Returns at Speed

The headline figure, 0.7% growth in a single quarter, is the kind of number that changes the tone of an economic debate. For an economy that has spent much of the past few years growing slowly, if at all, it is a clear step up. The Office for National Statistics, the body that compiles Britain’s official economic data, described the economy as having “grew robustly” in the July-to-September quarter, a phrase it does not use lightly. The growth was almost entirely driven by services, the part of the economy that covers everything from banking and law to software, retail and hospitality, and which accounts for roughly four-fifths of British output.

The timing matters as much as the size. The third quarter covered the summer months, a period when many forecasters had expected the economy to lose momentum. Predictions of a slowdown had circulated after the Iran war began, on the argument that higher energy prices and weaker global demand would drag on British activity. That slowdown did not arrive. Instead, the economy accelerated from the 0.5% recorded in the second quarter, and the annual rate of growth quickened to 1.9%. For a government that has made growth its central economic promise, the numbers are the strongest evidence yet that the economy is moving in the direction it wants.

1.1 What the ONS Reported on Thursday

The Office for National Statistics published the figures on Thursday, November 12, 2026, in its regular quarterly release. Gross domestic product, the total value of everything the country produces, rose 0.7% between July and September compared with the previous three months. That matched what economists had expected, according to a Reuters poll, which meant the surprise was not in the number itself but in how it was put together. Growth was broad, it was led by services, and it was strong enough to lift the annual comparison to its best level in nearly two years.

The statistics office also reported that the economy grew by 0.2% in September alone, the final month of the quarter. At the same time it revised down its estimate for August, from growth of 0.1% to no growth at all. Revisions of that kind are routine in economic statistics: the first estimates are based on partial data, and they are updated as more complete figures arrive. The revision to August does not change the story of the quarter, but it is a reminder that the numbers are estimates, not measurements, and that they will be revised again as more information comes in.

The ONS release also carried the detail that has dominated the reaction to the figures. The office said there was “widespread strength in industries which may be related to artificial intelligence”, a careful formulation that stops short of claiming a precise figure for AI’s contribution, but which points clearly in one direction. The industries most closely linked to the rollout of AI services, above all computer programming and consultancy, were among the fastest growing in the economy.

1.2 How the Quarter Compares With the Year So Far

Put the third quarter alongside the rest of 2026 and the picture is one of steady acceleration. The economy grew by 0.5% in the second quarter, and the 0.7% recorded in the third was the fastest quarterly expansion since the first quarter of 2024, when GDP also rose by 0.7%. The annual growth rate of 1.9% is the strongest since the fourth quarter of 2024, and on a rolling three-month basis growth was the fastest since May.

Deutsche Bank’s chief UK economist, Sanjay Raja, summed up the run in striking terms. “GDP is up 1.8% so far this year, and pushing at an annualised pace of just above 2.5% – marking the best first three quarters since the pandemic rebound. Strip out the pandemic years and you have to go back to 2017 to find the economy running this hot,” he said. The comparison with 2017 matters because it reaches back beyond the pandemic and beyond Brexit to a period when the British economy was growing at a pace that now feels distant. Whether the comparison holds depends on the final quarter of the year, but the first three quarters of 2026 are, on the official figures, the strongest start to a year since the post-pandemic rebound.

That framing should be treated with the caution that all economic comparisons deserve. The pandemic years distorted growth rates so sharply that any comparison with them is of limited use, and the annualised pace of just above 2.5% is an extrapolation, not a forecast: it assumes the recent pace continues, which it may not. Even so, the direction is clear. The economy is growing faster than it was a year ago, faster than most forecasters expected at the start of the year, and faster than the government’s own forecaster assumed only weeks ago.

2. Services Lead the Way

Services are the engine of the British economy, and in the third quarter they were the engine of its growth. The services sector expanded by 0.9% in the quarter, a strong performance that accounted for almost all of the overall 0.7% increase in GDP. Services cover a vast range of activity, from the professional firms of the City of London to the hotels, restaurants and shops of every high street, and when services grow at close to 1% in a quarter, the whole economy feels it.

The breadth of the growth is as important as its size. The ONS pointed to strength across the services sector rather than in a single industry, which suggests that the expansion was not the result of one unusual event or one lucky month. A narrow recovery, driven by a single sector, can reverse quickly. A broad one, spread across many industries, is more likely to last. That is the case the official figures make for the third quarter, even if the final verdict will depend on what happens in the months ahead.

2.1 The IT Sector Does the Heavy Lifting

Within services, the information and communication sector was the standout performer, growing by 2.1% in the quarter. The growth was mainly driven by increases in computer programming, consultancy and related activities, the industries at the heart of the AI rollout. The ONS said this industry has been the largest driver of GDP growth across 2026 as a whole, a statement that puts technology at the centre of the year’s economic story.

Computer programming and consultancy is a broad category. It covers the firms that build software, the consultants who help other companies install and use it, and the specialists who design the systems that run modern businesses. When companies invest in artificial intelligence, they rarely buy a single product. They hire programmers to adapt tools to their needs, consultants to redesign their workflows, and engineers to connect new systems to old ones. That spending shows up in the national accounts as growth in the IT sector, and in the third quarter it showed up in large amounts.

The scale of the increase, 2.1% in three months, is large for a sector of this size. It is also consistent with what has been reported elsewhere in the economy this year: businesses spending heavily on AI tools, data centres and the infrastructure that supports them. The question is whether that spending is a one-off wave of investment, which will fade once the first systems are in place, or the start of a longer shift in how British companies operate. The official figures cannot answer that question, but they show that for now the spending is real, it is large, and it is lifting the economy.

2.2 Widespread Strength Beyond Technology

The growth was not confined to technology. The ONS described “widespread strength” across services, and the overall services increase of 0.9% was too large to be explained by IT alone. Other service industries, from professional services to retail and hospitality, contributed to the expansion. That breadth is important because it suggests the economy’s improvement is not a statistical artefact of a single booming sector.

It is also worth noting what the services figures imply for everyday life. Services are where most Britons work, and growth in services usually means more hours worked, more hiring, and more income flowing to households. The official figures do not break down the employment picture in the same release, so the link between growth and jobs will only become clear when the labour market data arrive. But the direction of travel is encouraging for workers whose livelihoods depend on the service economy, which is most of the country.

There is a counterpoint, and it is one that economists will watch closely. Services growth of 0.9% in a quarter is strong, but it is also the kind of growth that can put upward pressure on prices, especially if it reflects higher demand for labour in a tight jobs market. The Bank of England watches services inflation closely for exactly this reason. For now, though, the immediate reading of the figures is positive: the part of the economy that matters most to most people grew, and it grew broadly.

3. The AI Effect: Real Spending, Real Output

The most striking feature of the third-quarter figures is the role of artificial intelligence. The ONS said there was “widespread strength in industries which may be related to artificial intelligence”, and the information and communication sector, the closest proxy for AI activity in the official data, grew by 2.1%. That is the clearest official evidence yet that AI spending is now large enough to move the national economy, not just the share prices of technology companies.

The story is not new, but its scale is. For several years, economists have debated whether AI would show up in productivity statistics or remain a promise. The third-quarter figures suggest it is showing up, at least in the form of spending: companies buying AI tools, hiring people to build and run them, and investing in the data centres and networks that make them work. That spending creates output, and output is what GDP measures. Whether it also creates lasting productivity gains, the kind that raise living standards over time, is a different question, and one that will take years to answer.

3.1 Where the AI Money Is Showing Up

The AI spending visible in the figures takes several forms. The most direct is the growth in computer programming and consultancy, where firms are paid to build, adapt and maintain AI systems. But the spending spreads wider than that. Companies that adopt AI tools often need new hardware, new data storage and new network capacity, and the firms that supply those things also grow. The ONS’s phrase “industries which may be related to artificial intelligence” is deliberately broad, and it covers this whole chain.

The pattern is familiar from earlier waves of technology. When the internet spread through business in the late 1990s, the first visible effect was a surge in spending on software, hardware and consultancy. Only later did the productivity gains arrive, as companies learned to use the new tools well. If AI follows the same path, the current spending is the first stage, and the benefits in efficiency and output will come later. That is the optimistic reading, and it is the one the government will want to encourage.

There is also a more concrete sign of the AI boom in the wider economy. Investment in data centres and the infrastructure that supports AI has been rising sharply, and the construction and equipment spending that goes with it feeds into GDP. The official figures do not separate out data-centre investment, but the strength of the IT sector and the broader services expansion are consistent with a large and growing flow of money into AI-related activity.

3.2 Why Economists Are Cautious About the Label

For all the excitement, economists are careful about attributing growth to AI. The ONS itself uses the cautious phrase “may be related to artificial intelligence”, and there are good reasons for that restraint. The official statistics do not have a category called “AI”. They measure industries, and the industries that are growing fastest happen to be the ones most closely associated with AI. That is suggestive, but it is not proof that AI is the cause.

Part of the growth in computer programming and consultancy may reflect ordinary demand for software and IT services that has nothing to do with AI. Companies have been digitising their operations for years, and the spending on that work would show up in the same industries. Separating the AI share from the rest is difficult, and the official statisticians have not attempted it. The result is that the AI story, while plausible and widely believed, rests on inference rather than direct measurement.

There is a second reason for caution. Spending on AI is not the same as benefiting from AI. A company that buys an expensive AI system and uses it badly has spent money without gaining much. The GDP figures capture the spending, not the benefit. If the current wave of AI investment turns out to be less productive than hoped, the growth it produces now could be followed by disappointment later. That is not a prediction, only a reminder that the link between spending and lasting prosperity is not automatic.

4. What Lagged Behind: Investment and Industry

Not every part of the economy shared in the third quarter’s strength. Business investment, the spending by companies on equipment, buildings and machinery, grew by just 0.4% in the quarter. That was half of what economists had expected in a Reuters poll, and the weakest growth since the start of the year. The contrast with the services figures is striking: the economy grew because people were buying and selling services, not because companies were investing in new capacity.

The weakness of business investment matters because investment is what determines how fast the economy can grow in the future. Services growth reflects demand today. Investment reflects confidence about tomorrow. When companies hold back on investment, it can mean they are uncertain about the future, or that borrowing costs are too high, or that they are waiting to see how the economy develops. Whatever the reason, the figures show that the business sector was more cautious than the services sector in the third quarter.

4.1 Business Investment Grows More Slowly Than Hoped

The 0.4% increase in business investment was well below the expectations of economists surveyed by Reuters, who had forecast roughly twice that rate. It was also the weakest quarterly increase since the start of the year. The shortfall is notable because it came in a quarter when the rest of the economy was performing strongly, which suggests that the caution is specific to investment decisions rather than a general lack of demand.

Several explanations are possible. Interest rates, while lower than their peak, remain high by the standards of the past decade, and that makes borrowing to invest more expensive. Uncertainty about the global economy, including the war in Iran and the state of world trade, may be making companies cautious. And some of the spending that might once have counted as business investment may now be showing up elsewhere, in the services figures, as companies rent cloud computing capacity and subscribe to software rather than buying equipment outright. The official figures do not distinguish between these explanations, and the truth is probably a mix of all of them.

The investment figures also carry a warning for the government. Its growth strategy depends on companies investing in new capacity, new technology and new skills. If investment stays weak while services growth is strong, the economy may be consuming more than it is building, and that is not a sustainable pattern over the long term. The third quarter’s figures do not prove that is happening, but they do show that the investment side of the economy needs attention.

4.2 The Monthly Picture: September Up, August Flat

The monthly figures tell a more uneven story than the quarterly headline. The economy grew by 0.2% in September, a modest but positive end to the quarter. August, however, was revised down from growth of 0.1% to no growth at all, meaning the economy stood still in the middle month of the quarter. July, the first month, carried much of the quarter’s strength.

Monthly GDP figures are volatile, and economists warn against reading too much into a single month. A flat August followed by a growing September is not a pattern, it is noise. But the monthly pattern does suggest that the quarter’s growth was front-loaded, with the strongest performance early on and a slower finish. That matters for the final quarter of the year: if the momentum faded in September, the fourth quarter may start from a weaker position than the headline figure suggests.

The revisions are also a reminder of how the statistics are made. The ONS publishes its first estimate of a month’s growth based on partial data, and revises it as more information arrives. The August revision, from 0.1% to zero, is small, but it is the kind of change that can alter the story of a quarter at the margins. The figures will be revised again, and the final picture of the third quarter may look slightly different from the one published on Thursday. For now, though, the headline stands: 0.7% growth, the fastest in two and a half years.

5. Britain Against Its Peers

Growth does not happen in isolation, and the third-quarter figures look even better when set against those of other advanced economies. Britain’s 0.7% expansion was the second-fastest in the Group of Seven advanced economies, just behind the United States. For a country that has spent much of the past decade trailing its peers on growth, that is a notable change of position.

The comparison matters because it speaks to a question that has dominated British economic debate for years: whether the economy is structurally weaker than its competitors, or whether its problems are cyclical and reversible. A single quarter cannot settle that question, but a second-place finish in the G7, driven by services and technology, is the kind of result that the government’s supporters will point to as evidence that the economy’s underlying performance is improving.

5.1 Second-Fastest in the G7

The Group of Seven, the club of the world’s largest advanced economies, provides the standard yardstick for international comparison. Britain’s third-quarter growth of 0.7% placed it second in the group, behind only the United States. The precise rankings of the other members depend on the timing of their releases, but the broad point is clear: Britain grew faster than France, Germany, Italy, Japan and Canada in the quarter, on the figures available.

That ranking is unusual. In recent years, Britain has often sat in the middle or lower half of the G7 growth table, held back by weak productivity, low investment and the disruption of Brexit. The third quarter reverses that pattern, at least for now. Whether it marks a lasting change or a one-off will depend on the coming quarters, and on whether the services-led growth can be sustained while business investment recovers.

The comparison also has a political dimension. Growth rankings are watched closely in Whitehall, and a strong showing is useful to a government that has staked its reputation on delivering growth. The chancellor will be aware that a single quarter’s ranking proves little, but he will also be aware that it is a lot easier to argue the economy is turning a corner when the official figures put Britain near the top of the G7 table.

5.2 The Comparison With the United States

The only G7 economy that grew faster than Britain in the third quarter was the United States, which has been the growth leader among advanced economies for much of the past two years. The American economy’s strength has been driven by consumer spending, technology investment and a large fiscal deficit, a combination that Britain cannot and would not want to copy directly. But the comparison is instructive: both economies are growing on the back of services and technology, and both are benefiting from the AI investment wave.

The similarities should not be overstated. The American economy is far larger, more dynamic and more productive than Britain’s, and its growth rate has been higher for longer. Britain’s third-quarter performance closes some of the gap, but it does not close it. What it does show is that the forces driving growth in the United States, above all the spending on AI and digital services, are also at work in Britain, and that they are powerful enough to lift the whole economy.

There is also a caution in the comparison. The United States has grown strongly while running large budget deficits and while its central bank has kept interest rates higher for longer. Britain’s fiscal position is tighter, and its room to support growth through public spending is more limited. The British economy will have to generate its growth largely from the private sector, which makes the weakness of business investment in the third quarter all the more important to watch.

6. The Political Stakes for the Chancellor

For Chancellor John Healey, the third-quarter figures are a welcome piece of news at a useful moment. They arrived barely two weeks after his budget on October 28, and they suggest that the economy is performing better than the forecasts on which that budget was built. The chancellor said the economy was growing at the fastest rate in almost 10 years, excluding the Covid-19 pandemic period, when lockdown restrictions distorted economic growth. It is a bold claim, and it will be tested by the figures for the rest of the year.

The political stakes are straightforward. The government has made economic growth its central promise, and its critics have argued that the promise is not being kept. Strong GDP figures give the chancellor evidence to push back, and they make it easier to argue that the budget’s measures are working. Weak figures would have done the opposite. The 0.7% growth rate does not settle the argument, but it shifts it in the government’s favour, at least for now.

6.1 A Boost Weeks After the Budget

The budget on October 28 was built on forecasts that now look cautious. The Office for Budget Responsibility, the independent body that forecasts the public finances, said at the time of the budget that it expected the economy to expand by 1.2% this year. That forecast, made only weeks ago, already looks out of date, as growth continues to exceed expectations. The Bank of England now expects GDP to expand by 1.6% this year, a full 0.4 percentage points higher than the OBR’s forecast.

The gap between the two forecasts is explained in part by timing. The OBR’s forecast was made before some of the stronger GDP data and upward revisions to past numbers were available, so it did not factor them in. The Bank of England’s forecast, made later, did. But the gap also reflects a genuine difference of view about how strong the economy is, and the third-quarter figures support the Bank’s more optimistic reading.

For the chancellor, the better-than-expected growth has practical consequences. Faster growth means more tax revenue and less pressure on the public finances, which gives the government more room to meet its spending plans without raising taxes or borrowing more. It also makes the budget’s arithmetic look better in retrospect. None of this is guaranteed to last, and the OBR will update its forecasts in due course, but for now the numbers are moving in the government’s direction.

6.2 Forecasts That Already Look Out of Date

The speed with which the OBR’s forecast has been overtaken is a reminder of how uncertain economic forecasting is. A forecast made at the end of October, based on the best available data, was out of date within two weeks. That is not a criticism of the forecasters: the data they work with are revised constantly, and the economy is hard to predict. But it is a reason to treat all forecasts, including the optimistic ones, with caution.

The Bank of England’s forecast of 1.6% growth for the year is itself an estimate, and it could be revised up or down as more data arrive. The fourth quarter, which is now under way, will determine whether the year ends closer to the Bank’s figure or the OBR’s. If growth in the final three months is strong, the year could end well above 1.6%. If it falters, the year’s total could fall back towards the OBR’s 1.2%. The third-quarter figures set a high bar, and the fourth quarter will show whether the economy can clear it.

What is clear is that the forecasting debate has shifted. A few months ago, the argument was about whether growth would be weak or very weak. Now it is about whether growth will be strong or very strong. That is a better argument for the government to be having, and it reflects a genuine improvement in the economy’s performance. But it is also a reminder that forecasts are not outcomes, and that the economy has a habit of surprising forecasters in both directions.

7. What the Bank of England Sees Next

The Bank of England, which sets interest rates, will be reading the third-quarter figures with a mixture of satisfaction and caution. Satisfaction, because stronger growth is good news for the economy. Caution, because stronger growth, especially in services, can put upward pressure on prices, and the Bank’s job is to keep inflation under control. The balance between those two concerns will shape its decisions on interest rates in the months ahead.

The Bank now expects GDP to expand by 1.6% this year, much stronger than the 1.2% forecast by the OBR. That upgrade reflects the stronger data and the upward revisions to past numbers, and it signals that the Bank’s economists believe the economy has more momentum than they previously thought. It does not, by itself, tell us what the Bank will do with interest rates, but it is part of the picture that its rate-setting committee will consider.

7.1 Growth Forecasts Revised Higher

The Bank of England’s upgraded forecast, from the 1.2% implied by the OBR’s budget numbers to 1.6%, is a significant change. It reflects not just the third quarter’s strength but also the revisions to earlier data, which showed the economy had been growing faster than previously thought. The Bank’s economists will have looked at the breadth of the services expansion, the strength of the IT sector, and the annual growth rate of 1.9%, and concluded that the economy’s underlying pace is higher than they had assumed.

Forecast upgrades of this size are not made lightly, and they are usually followed by questions about what they mean for policy. A central bank that believes the economy is growing faster than expected may be less inclined to cut interest rates, because it worries that lower rates could fuel inflation. Conversely, if it believes the growth is driven by productivity improvements, such as the spread of AI, it may be more relaxed, because productivity growth allows the economy to expand without pushing up prices. The Bank has not said which view it takes, and its next decisions will be watched closely for clues.

7.2 The Interest-Rate Question

Interest rates are the lever the Bank of England uses to manage the economy, and the third-quarter figures complicate its task. Strong growth in services, especially in a tight labour market, can push up wages and prices, which would argue against cutting rates. At the same time, weak business investment and the uncertain global outlook argue for keeping borrowing costs as low as possible to encourage companies to invest. The Bank must weigh these opposing forces, and the third-quarter figures pull in both directions.

For households and businesses, the interest-rate decision matters directly. Lower rates mean cheaper mortgages, cheaper business loans and more spending power. Higher rates mean the opposite. The Bank’s next move will be one of the most closely watched decisions of the coming months, and the third-quarter growth figures will be part of the evidence its committee considers. For now, the figures do not point clearly in one direction, and that uncertainty is itself a sign of how finely balanced the economy is.

There is one more consideration. The growth figures are for the economy as a whole, but they do not tell us how the growth is distributed. If the gains are concentrated in London and the south-east, or in the technology sector, while other regions and industries lag behind, the Bank’s national figures will not capture the full picture. The ONS does not publish regional GDP figures in the same release, so that question will have to wait for later data. It is, however, a question that will matter for how the growth is experienced by people outside the booming sectors.

8. What Remains Uncertain and What to Watch Next

The third-quarter figures are the best economic news Britain has had in some time, but they leave important questions unanswered. The most immediate is whether the growth can be sustained into the final quarter of the year and beyond. The monthly figures, with August flat and September growing only modestly, suggest the momentum may already be fading. The fourth quarter will provide the first test of whether the third quarter was the start of a stronger run or a peak.

The second question is about the nature of the growth itself. If the AI-driven expansion in services is the start of a productivity revolution, it could transform the economy’s prospects. If it is a wave of spending that produces little lasting benefit, the growth will fade as the spending slows. The official figures cannot distinguish between those two possibilities yet, and economists will be watching the productivity data for evidence of which one is happening.

The third question is about business investment. The 0.4% increase in the third quarter was the weakest since the start of the year, and it sits uneasily alongside the strong services figures. If companies remain reluctant to invest, the economy’s capacity to grow in the future will be limited, no matter how strong services are today. The investment figures for the fourth quarter will be watched as closely as the headline GDP number.

8.1 The Questions Without Answers Yet

Several specific questions remain open. The first is whether the ONS’s attribution of growth to AI-related industries will be confirmed by more detailed data, or whether the link will turn out to be weaker than the headlines suggest. The office’s careful language, “industries which may be related to artificial intelligence”, leaves room for both possibilities, and the detailed industry breakdowns due in later releases will give a clearer picture.

The second open question is about the labour market. The GDP figures do not tell us how many jobs were created, how fast wages grew, or whether the growth reached the people who need it most. The labour market data for the third quarter will fill in that gap, and they will matter as much as the GDP figures themselves. Growth that does not reach workers’ pay packets is growth of a limited kind.

The third question is about the global backdrop. The third-quarter figures were recorded against a difficult international picture, including the war in Iran and tensions in the Strait of Hormuz, where attacks on shipping have risen. The economy grew despite those headwinds, which is encouraging, but the headwinds have not gone away. A worsening of the global situation could still drag on British growth in the months ahead, and the fourth-quarter figures will show whether the economy’s resilience holds.

A final uncertainty concerns the figures themselves. GDP estimates are revised, sometimes substantially, and the third-quarter figure of 0.7% could be revised up or down as more complete data arrive. The August revision, from 0.1% to zero, is a small example of that process. Readers should treat the figures as the best available estimate, not as a final verdict, and should expect them to change.

8.2 The Bottom Line

Britain’s economy grew by 0.7% in the third quarter of 2026, its fastest pace in two and a half years, and the growth was broad, services-led and powered in large part by spending on artificial intelligence. The annual rate reached 1.9%, Britain ranked second-fastest in the G7, and the Bank of England now expects the economy to expand by 1.6% this year, well above the 1.2% forecast in the October budget. For the chancellor, the figures are a boost. For households and businesses, they are a sign that the economy is moving in the right direction. The coming days will provide the answers to whether the momentum lasts, whether business investment recovers, and whether the AI boom delivers lasting gains rather than a brief burst of spending. For now, the numbers speak for themselves: the British economy is growing again, and growing faster than almost anyone expected.
